38 year old asian male. Started on the big 3 in my early 30's. Father is bald (NW6, diffuse). Mother's father had no hair loss and uncles have hair albeit mature hairlines. Past few years I've had weaker/thinner hair on my hairline. Lately my hair in general seems softer/weaker. I've attached a picture from high school vs the present day. I know it's not bad (NW1.5) but my question is at some point will I be in the clear (mature hairline vs. balding)? I'm really worried about diffuse thinning like my dad. I'd rather recede slowly than go bald via diffuse thinning. If finasteride stops working I don't know what other options I have.
